Is it normal for parents/a parent to scream at, yell at, and "pop" (not a hit with a fist, but a light slap that leaves no marks or anything. just hurts like h3ll) their child when they don't get a school assignment done in time?

It depends there are 2 types of punishments parents use verbal and physical in my opinion I think physical punishments should not be used as a discipline action ! But I can see why other people think it's ok .

Yes, this has been normalized. But it is wrong.

Explanation:

Those 'pops' also count as spankings.

Even though it has been normalized doesn't mean it's right. A growing body of research has shown that physical discipline holds serious risk to children and teens. "Many parents just don't like to hear that their methods don't work.  On the international front, physical discipline is increasingly being viewed as a violation of children’s human rights. The United Nations Committee on the Rights of the Child issued a directive in 2006 calling physical punishment “legalized violence against children” that should be eliminated in all settings through “legislative, administrative, social and educational measures.” The treaty that established the committee has been supported by 192 countries, with only the United States and Somalia failing to ratify it." This statement is from https://www.apa.org/monitor/2012/04/spanking

"Physical punishment can work momentarily to stop problematic behavior because children are afraid of being hit, but it doesn’t work in the long term and can make children more aggressive." Graham-Bermann says.

Around 88 percent of psychologists condemn spanking. While 96 percent of psychologists say that it has horrible effects on children.

The website also states, " A study published last year in Child Abuse and Neglect revealed an intergenerational cycle of violence in homes where physical punishment was used. Researchers interviewed parents and children age 3 to 7 from more than 100 families. Children who were physically punished were more likely to endorse hitting as a means of resolving their conflicts with peers and siblings. Parents who had experienced frequent physical punishment during their childhood were more likely to believe it was acceptable, and they frequently spanked their children. Their children, in turn, often believed spanking was an appropriate disciplinary method."

Ultimately, while it is 'normal' it's wrong and if you do decide to have children, remember that physical discipline should be something you never resort to. But other than that I do suggest you do your own research and if your parents/parent/guardian isn't hostile, maybe try talking it out with them.

since you have not provided the options here i   am going to give you general overview about hormone.hormone are actually the part of endocrine system in our body and produced by the endocrine glands. the hormones act like a chemical messenger   within human body. once produce by the glands they   travel through the blood stream and reach at specific or target tissue and organs   which result in control of our body function. the hormones are specific in their work and work on only the targeted tissue or organ   . with the of hormone endocrine system regulate the heart rate , metabolism, our mood and   growth as well as the development and even the sleeping cycle etc. they actually are the messenger for body cell and organs .
